"I'm trying to breathe more than anything," she tells ESSENCE.com. "I'm really just trying to breathe through this. I don't think I've been this excited my entire life."

Ambrosius is nominated for two Grammys, including Best R&B Song for "Far Way," off her debut solo album, Late Nights and Early Mornings. As a member of Floetry, she and partner Natalie Stewart were nominated for five Grammys but never took home a golden gramophone. "[Winning] is all I've ever wanted," she says.

Already hard at work on her sophomore solo effort, the UK-born singer is set to go on a mini U.S. tour this summer, where she'll premiere new material. "Almost like a live unplugged -- real intimate vibe so people can really feel it," she says, describing the new album's sound.
